1. PAINPOINT DRIVEN OPENING

Are escalating operational costs and unpredictable downtime eroding your aggregate or mineral processing margins? Key challenges in primary crushing operations often include:

Excessive Downtime for Maintenance: Frequent liner changes and mechanical adjustments halt your entire production line, costing thousands per hour in lost throughput.
Unplanned Breakdowns from Shock Loads: Tramp metal and uncrushable materials cause catastrophic failures, leading to expensive component replacement and extended, unscheduled stoppages.
Inconsistent Product Gradation: Worn or poorly adjusted jaws produce offspec material, forcing recrushing and increasing wear on downstream equipment.
High Operational Costs: Soaring energy consumption per ton of processed material directly impacts your bottomline profitability.
Rigidity to Feed Variation: Inability to handle varying feed sizes or compositions without manual intervention reduces overall plant flexibility.

What if a primary crusher could directly address these issues with robust engineering focused on reliability and costperton efficiency? The solution requires a machine built not just for power, but for predictable, lowcost operation.

2. PRODUCT OVERVIEW

The Private Label JC5000 is a highcapacity, singletoggle overhead eccentric jaw crusher engineered for heavyduty primary crushing in quarrying, mining, and demolition recycling applications. Its design focuses on delivering maximum availability and the lowest possible cost per tonne in demanding 24/7 operational environments.

Operational Workflow:
1. Feed Intake: Large runofmine or blasted feed (up to 1300mm) is directed into the deep, nonchoking crushing chamber.
2. Crushing Action: The aggressive elliptical stroke of the overhead eccentric shaft forces the moving jaw to apply high inertia force at the nip angle, effectively breaking even the hardest granite or abrasive basalt.
3. Discharge & Clearance: The hydraulic toggle release system allows for rapid clearing of stalled cavities by instantly opening the closedside setting (CSS) to release blockages.
4. Gradation Control: Product size is consistently maintained via a simple, repeatable CSS adjustment using hydraulic shims, ensuring uniform feed for secondary crushers.

Application Scope & Limitations:
Scope: Ideal for primary reduction of hard rock (compressive strength up to 400 MPa), concrete demolition debris, and runofquarry stone. Suitable for both stationary plants and large mobile tracked setups.
Limitations: Not designed for ultrafine product sizing; optimal performance requires prescreening to remove excessive fines. Requires a stable, reinforced concrete foundation and appropriate feeding equipment matched to its intake dimensions.
